ZCAT3618-2630D

Overview

The TDK ZCAT3618-2630D is a two-piece clamp-on ferrite core designed for flat cables. It features an internal aperture of 26mm and dimensions of 33.5mm x 17.5mm x 11.5mm. The component utilizes TDK's 30 material, providing an impedance of 30Ω at 25MHz, 150Ω at 100MHz, and 30Ω at 500MHz. It operates within a temperature range of -40°C to 85°C and complies with RoHS and REACH standards.

Feature Summary

• Two-piece snap-fit design for easy installation on existing flat cables without disconnection
• Optimized for high-frequency electromagnetic interference absorption in the 50MHz to 500MHz range
• Specifically engineered geometry to accommodate 20-wire flat cables

Applications

• Electromagnetic compatibility (EMC) suppression for electronic musical instruments
• Noise reduction for video game consoles and peripherals
• Interference mitigation in office equipment such as copiers and printers

Procurement Notes

Verify the specific suffix designation when ordering, as variants like ZCAT3618-2630D-BK may exist. Confirm that the target cable width does not exceed the 26mm internal aperture. Ensure compliance requirements match project specifications, noting standard RoHS and REACH certification. Cross-reference datasheets for precise mechanical tolerances before integration into final assemblies.

Selection Notes

Select this component when dealing with multi-conductor flat ribbon cables rather than round wires. The 26mm aperture accommodates up to 20 wires. Choose based on required impedance profiles at specific frequencies; this model peaks at 100MHz. Consider the two-piece form factor for retrofitting or space-constrained environments where traditional through-hole cores are impractical.

Part Context

This part belongs to the ZCAT series of clamp-on ferrite cores from TDK. These components are distinct from single-piece rings due to their split construction, allowing them to be clamped around cables already connected to devices. The series offers various materials and sizes to address different frequency ranges and cable diameters.

Replacement Considerations

Direct substitutes include other TDK ZCAT models with matching aperture sizes and similar impedance characteristics. Verify that alternative parts support the same flat cable thickness and width constraints. Ensure environmental ratings and material composition meet original equipment specifications.
